Last updated: May 2026 · Thermal springs and a beach like nowhere else
Kythnos (also called Thermia for its hot springs) is a gentle, rolling island close to Athens, beloved by Greek families and sailors. It has more than 70 beaches, a famous double-bay sandbar, healing thermal waters and two of the prettiest inland villages in the western Cyclades.

🏖️ Beaches
1. Kolona
The island's signature beach: a slender sandbar linking Kythnos to the islet of Agios Loukas, with calm sea on both sides. Reach it by boat from Loutra or a bumpy track; arrive early for the magic.
2. Apokrousi & Episkopi
Two long, sandy, tamarisk-backed beaches on the west coast, the most family-friendly on the island.
3. Kanala
A pine-shaded resort village on the southeast coast with sandy coves and the church of Panagia Kanala, the island's patron.
♨️ Thermal Springs
4. Loutra Hot Springs
Kythnos has been a spa destination since antiquity. At Loutra, naturally hot, iron-rich water flows into the sea, you can soak for free where the stream meets the beach, or visit the historic hydrotherapy centre.
🕳️ Villages & Caves
5. Dryopida
A captivating inland village of red-tiled roofs tumbling down a ravine, more mainland than Cycladic in feel, with a folklore museum and traditional crafts.
6. The Katafyki Cave
Beneath Dryopida lies one of the largest caves in Greece, used as an iron mine and a wartime shelter. Guided visits run in summer.
7. Chora (Messaria)
The whitewashed capital, threaded with painted floral motifs on the lanes and dotted with old churches, a quiet, authentic Cycladic town.
🚶 Active & Experiences
8. Hike the Restored Trail Network
Kythnos has an excellent waymarked trail system linking villages, beaches and the ruined medieval capital of Vryokastro (Kastro tis Orias).
9. Sail & Anchor at Fykiada
The bay beside Kolona is a favourite yacht anchorage; in summer day boats and sailing trips explore the quiet northern coves.
10. Taste Local Kythnos
Try sfougato (a local cheese-and-herb omelette), thermiotika almond sweets and the island's honey and cheeses at the tavernas of Loutra and Chora.
